CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application is a divisional of, and claims priority from, U.S. patent application Ser. No. 11/078,086 filed on Mar. 11, 2005, which is incorporated herein by reference in its entirety.

BACKGROUND

As the popularity of digital media continues to gain momentum, more and more users are using computers as their primary source of media playback. This trend is, in part, driven by the superior versatility of a programmable computing device, as compared to a dedicated, single purpose electronic device, such as a DVD player. For example, a computer may be programmed to playback and view many types of media, such as audio, video, graphics, documents, web content, etc. The extensiveness and diversify of the network and program interfaces found in computers are often essential to gain access to online digital media content. The ability to access the Internet also allows users to obtain enhanced content related to the media from online content providers.

Unfortunately, a conventional computer is typically not as user-friendly as a typical electronic media device. To play media content, the user interface offered by conventional computers often require more effort than pushing one or two buttons on a remote control. Also, users often have to use applications that are provided by third party online providers in order to receive the desire content offered by those providers.

A user-friendly way for third party providers to provide content to computer users without the need for a user to perform extensive setup and monitoring using the providers' applications continue to elude those skilled in the art.

DETAILED DESCRIPTION

The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the examples and the sequence of steps for constructing and operating the examples. However, the same or equivalent functions and sequences may be accomplished by different examples.

The systems and methods described herein are directed toward launching a third party application in a media center module using a contextual link. The media center module is configured to enable the third party application to register with the module and to associate a contextual link corresponding to the third party application with a context provided by the media center module. In response to a request for information related to the context, the media center module is configured to direct to a location associated with the contextual link. The media center module is further configured to provide to the location data that identifies the context. In response to the provided data, the location is populated with the requested information. Thus, the use of conditional link enables a third party application to register to be a context handler for a media center module.

FIG. 1 illustrates an example system 100 for handling digital media content. The system 100 may include software modules in computing device 105 and servers 143-144. Computing device 105 includes media center module 110 configured to provide an environment for applications to provide digital media content to computing device 105. Media center module 110 is also configured to manage the applications and the digital media content. For example, media center module 110 may interact with third party applications 136-137, which may be configured to communicate with third-party provider services 146-147 to provide digital media files 120 and other related information.

Media center module 110 may be implemented as an application or a component of the operating system for computing device 105. An example of media center module 110 is WINDOW® XP Media Center Edition. As shown in FIG. 1, media center module 110 may include a graphical user interface 113, link structure 115, and registration manager 117.

The functionalities and third party application associated with media center module 110 are typically organized with link structure 115. Link structure 115 includes multiple links that point to local locations in computing device 105 for media content and applications, such as third party applications 136-137. The links may also point to network locations in other devices, such as server 143-144. Links included in link structure 115 are presented by graphical user interface 113 for selection and may serve as entry points for applications associated with media center module 110. For example, the locations indicated by the links may be associated with data for launching applications that handle media content. Graphical user interface 113 is configured to enable a user to interact with media center module 110. Typically, graphical user interface 113 organizes the functionalities of media center module 110 with links included in link structure 115.

Registration manager 117 is configured to register applications with media center module 110. For example, registration manger 117 may be configured to handle registration for third party applications that are installed on media center module 110, such as third party applications 136-137. In particular, third party applications 136-137 may have entry points that enable a user to access the applications from media center module 110. The entry points are typically represented by links. Registration manager 117 is configured to incorporate these links into link structure 115. Graphical user interface 113 may access link structure 115 to present the links to the user for accessing third party applications 136-137. Typically, link structure 115 includes a primary link for each of the third party applications 136-137. The primary link serves as the main entry point for the corresponding application.

Registration manager 117 may also include a conditional link for a third party application in link structure 115. A conditional link points to a location that is different from the location associated with the primary link for the third party application. A conditional link is typically associated with a condition. When the condition exists, the conditional link replaces the primary link as the main entry point for the third party application. The location associated with the conditional link may serve as a unified place for aggregating asynchronous notifications about new content provided by the third party application.

For example, third party application 136 in media center module 110 may specify a conditional link that points to a page for accessing new content when they are available. Third party application 136 may receive the new content from third party provider services 146. Third party application 136 may notify media center module 110 to use the conditional link as the main entry point when the new content has been downloaded. The media center module 110 may display a message in graphical user interface 113 about the new content. In this manner, a user may be informed of the new content without having to launch third party application 136. Also, the user is automatically directed to a location for accessing the new content when the user selects to launch the third party application. In one embodiment, media center module 110 may include a page dedicated to new content notifications along with conditional links for the third party applications that provide the new content.

Digital media files 120 are digital media content managed by media center module 110. Digital media files 120 may include any type of content, such as video files, audio files, documents, graphics, pictures, web pages, or the like. Media center module 110 may be configured to organize digital media files 120 with the context of the files, such as the artist, album, genre, producer, director, or the like. A user of digital media files 120 may desire to obtain more information about a particular file or find other media content similar to the file. Media center module 110 may be configured to allow third party applications to register as context handlers to provide information to the user in a particular context. For example, link structure 115 may include locations where contextual links associated with each particular context are stored. Media center module 110 may include links of the third party applications registered as context handlers in link structure 115 at locations associated with the registered context.

Media center module 110 may be configured to enable a user who desires contextual information to select and interact with context handlers. For example, if a user chooses a particular song in media center module 110 and selects to find other media content in the same context as the chosen song, media center module 110 may direct the user to the handler for that context. Media center module 110 may provide contextual information of the chosen song to the context handler so that the handler may provide media content related to the context to the user. For example, media center module 110 may provide the contextual information as a HTML Post message to the third party application that is registered to be the context handler.

FIG. 2 illustrates an example implementation of a conditional link in media center module 110 shown in FIG. 1. In this example, a third party application named More Music is registered with media center module 110. As shown in FIG. 2, link structure 115 includes entries that are associated with More Music. For illustrative purpose, only a few entries in link structure 115 are shown. A third party application may registered with media center module 110 in any manner, such as by communication through an API offered by media center module 110 or by providing a setup file with setup information.

Typically, each application registered with media center module 110 is identified with a global universal identification (GUID) in link structure 115. In FIG. 2, More Music is identified by “appID A”. Link structure 115 may also include links 211 associated with More Music. Each of the links 211 may also be identified with a GUID. In this example, two links are included for More Music and are identified as “linkID A” and “linkID B”. Each of the links points to a specific location from which program codes associated with More Music can be retrieved for launching the application. The locations associated with the links may be a local location, such as a local file, or a network location, such as an Internet address. In this example, “linkID A” is associated with a local file provided by More Music. The “linkID B” is associated with a web page provided by a More Music network server.

Link structure 115 may also include entry points 213 for More Music. These entry points are provided by More Music to media center module 110 during registration. As shown in FIG. 2, a main entry point and a conditional entry point are included for More Music. The main entry point provides program access to More Music in media center module 110 under normal circumstances. The conditional entry point is an alternative access location for More Music under a certain condition. Typically, media center module 110 provides program access to a user using the main entry point. The application associated with More Music may determine that the certain condition exists and may notify media center module 110 to use the conditional entry point for program access to More Music.

In FIG. 2, example screens of graphical user interface 113 for media center module 110 are shown to illustrate the use of a conditional link. Screen 203 shows a main music page provided by graphical user interface 113. Screen 203 includes multiple entry points for launching third party music programs in media center module 110. One of the entry points is entry point 207 for More Music. The entry point corresponds to the entry points 213 in link structure 115. A user may select entry point 207 to launch an application associated with More Music. Under normal circumstances, media center module 110 is configured to launch More Music with the main entry point associated with “linkID A”. In response to the user selection, the graphical user interface 113 displays the main launch screen 204 for More Music. However, if media center module 110 receives a notification from the More Music application to implement the conditional entry point, media center module would launch More Music with the conditional entry point specified in link structure 115. In this example, the conditional entry point is implemented when there is new music content offered by More Music. In response to the user selecting to launch More Music, the graphical user interface 113 displays the new music screen 205.

FIG. 3 illustrates an example implementation of a contextual link in media center module 110 shown in FIG. 1. The example in FIG. 3 is implemented when the third party application for More Music is registered with media center module 110 and requests to be a context information handler. The data in link structure 115 associated with More Music includes a contextual link 307, which is the entry point for the application for More Music. A third party application may register to be a handler for any context provided by media center module 110. In this example, More Music registers to be a context handler for a context in music. Link structure 115 includes More Music's entry point link for the music genre context. Media center module 110 is thus configured to direct requests for information for music genre to contextual link 307 associated with More Music.

In FIG. 3, an example screen of graphical user interface 113 for media center module 110 is shown to illustrate the use of a contextual link. Screen 303 shows a music page provided by graphical user interface 113 to access music files that are managed by media center module 110. The music files may be organized in accordance with contextual information, such as genre. In this example, screen 303 shows songs (e.g. music files) in the rock genre that are available for user selection. As shown in FIG. 3, song 310 has been selected. Graphical user interface 113 then provides menu 312 to enable the selection of actions available for song 310. One of the selections includes action 314 for retrieving information in the current context of the rock genre. Since More Music registered to be the handler for music genre, the selection of this action causes contextual link 307 to be activated and the direction to a location associated with More Music. Media center module 110 is configured to provide the contextual information to More Music so that More Music can provide information associated with the current context. For example, media center module 110 may provide the contextual information as POST data in an HTTP request. In this example, the contextual information may include the information that the current context is the rock genre. More Music may include a page at the location specified by the contextual link with information related to the rock genre.

It is to be appreciated that a third party application may register to be a handler in multiple context. Also, the contextual information provided by the media center module to the registered third party applications may include any type of data about a media, such as genre, artist, song, album, or the like.

FIG. 4 shows an example process 400 for incorporating a conditional link for navigating to a media application. Process 400 may be used by a media center module to enable a third part application to provide a conditional entry point for the application. At block 403, a primary link and a conditional link associated with an application are identified. The primary link serves as the main entry point for launching the third party application and the conditional link is the alternative entry point that is implemented under a certain condition. The links may be provided to the media center module when the third party application registers with the module.

At block 405, the links are incorporated into a link structure associated with the media center module. The link structure includes entries for each application that has registered with the media center module. At block 407, the entry point for the application in a graphical user interface provided by the media center module is associated with the primary link. Thus, a selection of the entry point will cause the media center module to direct to the location indicated by the primary link.

At block 409, data is received from the application by the media center module. The application may provide any type of data to the media center module, such as media content and related information. The application may also provide a notification to the media center module to use a conditional link. For example, the application may be configured to provide some requested media content to the media center module. When the downloading of the media content has been completed, the application may notify the media center module to use the conditional link, which points to the location for accessing the newly downloaded media content.

At block 411, a determination is made whether a notification to use conditional link is provided by the application. If not, process 400 goes to return block 421. If a notification has been provided, process 400 goes to block 413 where the application entry point is associated with the conditional link. At decision block 415, a determination is made whether the application entry point is selected. If not, process 400 goes to return block 421. If the entry point has been selected, process 400 continues at block 417 where the media center module directs to the location indicated by the conditional link. At block 419, the application entry point is associated back to the primary link. Process 400 goes to block 421 where the process is returned to perform other tasks.

FIG. 5 shows an example process 500 for incorporating contextual links for navigating to a media application. Process 500 may be used by a media center module to enable a third party application to provide information associated with a context. At block 502, contextual links associated with an application are identified. Each contextual link is related to a specific context and serves as the entry point for the application. The contextual links may be provided to media center module when the application registers with the module as context information handler.

At block 504, the contextual links are incorporated at locations in a link structure corresponding to the contexts of the contextual links. At block 506, a selection of an item provided by the media center module is received. The item may include any media content, such as an audio file, a video file, a document, or the like. At block 508, a selection to access information associated with the item is received. At block 510, the context associated with the item is identified. At block 512, a contextual link associated with the selected item is determined. At block 514, the media center module directs to the location associated with the contextual link. The media center also provides data about the context to the location. For example, the data may be provided as POST data in an HTTP request to the location.

The example code below may be used by a media center module to provide an Application Program Interface (API) for a third party application to registered with the module.

MediaCenter.Registrar RegisterApplication(string appGuid, string name, string companyName); UnregisterApplication(string appGuid); RegisterLink(string linkGuid, string name, string description, string url, string startImageUrl, string thumbnailUrl, int capabilities, string appGuid); UnregisterLink(string linkGuid); AssociateLink(string linkGuid, string associationType, string category); DisassociateLink(string linkGuid, string associationType, string category);

The example code below may be used by a third party application to interact with the API of the media center module shown above.

reg = MediaCenter.Registrar; string installDir = “file://c:\Program Files\FooBar Inc\MoreMusic”; // Registering an extensibility application: string myAppGuid = “{e9dc1cb5-5b17-4b21-bd66-5e0c2efe8175}”; reg.RegisterApplication(myAppGuid, “MoreMusic”, “FooBar, Inc.”); // Registering a link: string myLinkGuid = “{c1bc45e2-c4d8-4226-a44f-a2bf38532618}”; reg.RegisterLink( myLinkGuid, “MoreMusic”, “MoreMusic is your one-stop shop for all music, all the time.”, installDir + “home.htm”, installDir + “startimage.png”, installDir + “thumbnail.png”, 0, myAppGuid); // Associating a link with various places within Media Center: reg.AssociateLink(myLinkGuid, “Programs”, “”); reg.AssociateLink(myLinkGuid, “MoreWithThis”, “Artist,Album,Song,Genre”); reg.AssociateLink(myLinkGuid, “Services”, “Music,Radio”); // Registering and associating a “new for me” link: string myNewLinkGuid = “{7abeaef5-2839-4c30-a8dd-a6168aa37db4}”; reg.RegisterLink( myNewLinkGuid, “New albums available from MoreMusic”, “MoreMusic has some new albums you might be interested in purchasing.”, installDir + “newforme.htm”, installDir + “startimage.png”, installDir + “thumbnail.png”, 0, myAppGuid); reg.AssociateLink(myNewLinkGuid, “NewForMe”, “”); // Removing a “new for me” link (unregisters and removes associations): reg.UnregisterLink(myNewLinkGuid); // Removing the whole application (unregisters app plus all its links and associations): reg.UnregisterApplication(myAppGuid);

The example code below may be incorporated in an extensible markup language (XML) file that serves as input to the API shown above.

<application appGuid=”{e9dc1cb5-5b17-4b21-bd66-5e0c2efe8175}” name=”MoreMusic” companyName=”FooBar, Inc.”> <link linkGuid=”{c1bc45e2-c4d8-4226-a44f-a2bf38532618}” name=”MoreMusic” description=“MoreMusic is your one-stop shop for all music, all the time.” url=“.\home.html”; startImageUrl=“.\startimage.png” thumbnailUrl=“.\thumbnail.png” capabilities=”0”> <association type=”Programs” /> <association type=”MoreWithThis” category=“Artist,Album,Song,Genre” /> <association type=”Services” category=“Artist,Album,Song,Genre” /> </link> <link> linkGuid=”{7abeaef5-2839-4c30-a8dd-a6168aa37db4}” name=”New albums available from MoreMusic” description=“MoreMusic has some new albums you might be interested in purchasing.” url=“.\newforme.html”; startImageUrl=“.\MoreMusic\startimage.png” thumbnailUrl=“.\MoreMusic\thumbnail.png” capabilities=”0”> <association type=”NewForMe” /> </link> </application>
